EDIT Jan. 11: Please try
this self-installing version of ICS first. If it doesn't work for you, try the manual install below.
I was able to install ICS to my Telus P4000 (Titan/Mogul) stock rom which only ships with WModem software. Both USB and WMWiFiRouter works, but I haven't tested BT. If anyone else gets it working, please report your device model for others to find.
